inc::Module::Install - Module::Install configuration system.

This module first checks whether the inc/.author directory exists, and
removes the whole inc/ directory if it does, so the module author always
get a fresh inc every time they run Makefile.PL. Next, it unshifts inc
into @INC, then loads Module::Install from there.

Below is an explanation of the reason for using a loader module:

The original implementation of CPAN::MakeMaker introduces subtle
problems for distributions ending with CPAN (e.g. CPAN.pm,
WAIT::Format::CPAN), because its placement in ./CPAN/ duplicates the
real libraries that will get installed; also, the directory name ./CPAN/
may confuse users.

On the other hand, putting included, for-build-time-only libraries in
./inc/ is a normal practice, and there is little chance that a CPAN
distribution will be called Something::inc, so it's much safer to use.

Also, it allows for other helper modules like Module::AutoInstall to
reside also in inc/, and to make use of them.
